Welcome to the forum. You do not mention the year, make and model of your coach, but the loads you mention specifically run off the coach (house batteries) typically. After 10 months of sitting idle/uncharged they are probably dead. If they are dead you may have to charge them using a stand alone battery charger (or boost) in case your use/store latching relay does not operate (close) because of the dead battery condition. Normally when on SP (shore power) you must turn on the use/store switch in order to charge coach batteries. Depending on the coach power configuration SP can charge both coach and chassis batteries and/or when engine is running the alternator can charge both batteries also.
